act; to the reel, the sheets falling stretch of the moving ribbon, whichextends To all whom it may concern: Be it known that l, BURNIl-IAM G.STICK- standards 2l, 25 erected upon a base 26. which is separable i'romthe base 5. The slots 20 2,1. are open so that-tho spool may be withdraw n .tl'icretrom,

wound upon a spool, and is hanail-011mm to irovidcd upon the gadgeon thedclia eryside of the cylinderand thence and a winch ,Wjis 1Dforrowinding iio the spool. A brake 28 produces enough friction on thespool flange tocause the ribbon to Wind with sufiicient tightness uponthe comes filled with the ribbon and sheets, and

when the reel. is full, it may be lifted out of the slots and replacedby an empty reel.

The roll 29 feeds or drives the periphery or surface of the reel. 14:.so that the rate at which the ribbon 11 is-wound thereon does not varyas the reel fills. The roll 29 is driven by means of an endless crossedcord 38, extending from a large sheave 39 upon the stencil cylinder to asmall sheave 40 upon the roll, the sheaves being propor tioned to enablethe ribbon to travel at about the peripheral speed of the stencilcylinder 1. In case short sheets are being stenciled,

. the cord 38 may be shifted to sheaves 41, 42,

to cause the roll 29 and reel 14 to rotate more slowly, relatively tothe stencil cylinder. The portion 17 ofthe ribbon is carried forwardlybeneath the roll'29, and may be guided partly around-the same asillustrated.

When the stencil cylinder is turned by hand, it is usually arrested ateach operation, and the handle 6 or a part thereof'is ,set back againsta movable stop shown. dia

grammatically at 43, Fig. 2, to position the cylinder to receive thefresh sheet. It not being desirable to arrest the reelsuddenly in thismanner, I prefer to effect a loose con nection between the stencilcylinder and the reel, which will permit the latter to continue inrotation after the stencil cylinder is arrested. To this end, the roll29 is mountedloosely upon its axle 30, and the latter is provided withan arm 44:, upon which is cariied a pawl 45 to engage a ratchet wheel 46ficed upon the roll 29 to drive the same Without restraining itsindependent, advance movement -I also prefer to introduce a yieldingconnection or spring 4z7 between the sheave 40 and the axle 30, so as tomake it easier to start the apparatus in motion as each sheet 7 isinserted into the bite of the cylinder and the. pressure roll 10; thespring rendering it practicable to advance the-stencil cylinder Withoutfirst overcoming the inertia of the reel and the spool and the coils ofribbon thereon;

The base 26 is connected 'to the base by means of hooks 48 pivoted uponone base and catching over pins 49 upon the other; the relation beingsuch that the roll 12 lies under the delivery side of the stencilcylinder. \Vhen it is desired to remove the sheets from the reel, thehooks48 are cast off, and the reel frame 26 separated from thestenciling frame 5, and set by itself upon a table. Then the winch 27 isturned to rewind the ribbon upon the spool l6. As the reel 14 pays offthe ribbon, the sheets emerge from the coils of ribbon and ride alongthe stretch ll of the ribbon, and are discharged therefrom, as it passesdown around the roll-12, and are deposited upon the table or in asuitable receptacle placed upon the table.

The ends of the ribbon are preferablydetachabl y connected to the reeland spool; as for instance the 1, may he slipped beneath thin springclips 51 carried upon the empty reel 14; and simi- "lar clips may beprovided upon the core of the spool.

Variations may be resorted to within the scope of the invention, andportions of the improvements may be used without others.

I'laving thus described my invention, I claim:

l. in a stcncillug machine, the combinationwith a stcncil-cvlindermechanism including a. stop which arrests the cylinder at eachrevolution, of a reel carrying a ribbon for holding the stenciledsheets, a roll against which the periphery of said reel rests, and anoperative connection between said roll and said cylinder constructed topermit overrunnii'ig of the reel when the stencil cylinder is brought torest.
